Abstract
The wide spread of smart phones and their capabilities made them an important part of many people's life over the world. However, there are many challenges facing these devices such as: low computing power and fast energy drain from their batteries. One solution is to use mobile cloud computing services to run certain tasks at the cloud and returning back the results to the mobile device saving space and processing power. In this research, we introduce efficient Mobile Cloud Computing model based on the Cloudlet sheme. In our model, the mobile device don't need to communicate with the enterprise cloud server and instead contact the Cloudlet directly using cheaper technologies such as Wi-Fi, and no need for 3G/4G. Also, we propose a master-cloudlet management scheme to organize the communication between the cloudlets themselves. Our efficient mobile cloud computing model can be applied in many environments including universities and hospitals were big amounts of data is collected, stored and processed. The real implementation results show that our model out performs classical non-cloudlet mobile cloud computing models.
